To all whom it may concern:

Be it known that I, J AGUB SCHWARTZMAN a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in lVire Fabrics, of whichthe following is a specification.

This invention relates to wire metallic fabrics, the object of theinvention being to provide an improved fabric of this characterparticularly adapted for use in connection with spring mattresses, whichwill be simple in construction, durable in use, and comparativelyinexpensive to manufacture, especially in View of the fact that itrequires a minimum amount of wire in its construction, made up of animproved form of links, quickly and inexpensively assembled, and inwhich the pull ,on the several links of the fabric will be in a straightdirection lengthwise of the fabric, and which links are so constructedand assembled that they will not draw the edges ofthe fabric toward themiddle by reason of the lengthwise pull on the links, while at the sametime the fabric will be unusually resilient and may be readily foldedalong longitudinal lines, which is desirable when the fabric is to beapplied for use in folding cots, divans and other folding structures.

The present improvement is a, division of my Patent No. 1,116,500, datedNovember 10, 1914. s

In the drawings accompanying and forming part of this specification,Figure 1 is a plan View of a plurality of links of the exact size asusually used, assembled; Fig. 2 is a plan view showing the improvedfabric made up of a number of units or links; Fig. 3 is a detail view,full size, of one of the improved links for the body of the fabric; Fig.4 is an edge view of the link shown in Fig. 3; and Fig. 5 is a detailView illustrating another way of assembling the same form of links, thelinks being shown full size.

Similar characters of reference indicate corresponding parts throughoutthe several figures of the drawings.

In the form shown, the fabric is made up of a series of interconnectedor interwoven units or links 2, each comprising a pair of relativelystraight portions 3 and 4 running in substantial parallelism with eachother and connected at their ends by a cross-forming portion 5, thusforming a link somewhat resembling a capital letter U.- The straightportions 3 and 4 of the link terminate in hooks or loops 3 and itrespectively at one end of the link, these hooks being in alinement withthe straight portions and are closed when the link is made; in otherwords, before the links are assembled and notsubsequent to theassembling of the links. At the opposite end, or what may be consideredthe head portion, of the link, each of these lengthwise extendingportions v3 and 4 merges into an angular-formed portion 6 made up of apair. of inclined portions 7 and 8, each of which may be slightlycurved, which inclined portions 7 and 8 at their juncture points areoffset one from the other as at 9, that is, it is given a half twistwhereby the several links may be readily interwoven with each other, theinclinedportion 7 in turnbeing bent inwardly as at 10 to form an eye orloop 11 of somewhat triangular form and therefore resembling some whatthe shape of an. inverted V, such loop or. eye terminating in the crossmember 5. Each angular formed portion extends'outwardly so that the linkat this point is of greater width than at any other point thereof, whilethe cross member 5 is located inwardly of the extreme end of the linkandis comparatively short, and the straight por-.

tions 3 and 1, if continued, wouldmerge into the inclined portions 10relatively close to the outer ends of the cross portion 5. In short, thehead of each link is considerably, wider than the space between thestraight portions 3 and 4 thereof for the purpose hereinafter stated.The angular portions of the link hereinbefore described are for thepurpose of permitting an efiicient and effective interlocking orinterweaving of one link with a companion link in the manner shown inFigs. 1 and 2, in which it will be observed that the companion links orunits are, as it were, twisted together, this being permitted by reasonof the offset portions 9 of each link which'constitute the connectingpart between the inclinedportions forming the triangular portion of thelink at this point.

When the several units or links have been assembled in the manner shownin Figs. 1

and 2, they are connected to a supporting or cross-angle bar by helicalsprings 13, for

which purpose intermediate end links 14 are provided with hooked ends 15for connection with the eyes 11 of the several links.

In the form shown in Fig. 5 the units or links instead of beingconnected or interwoven directly, are connected by meansof a ring 16which is interwoven with the triangular portions of the link. It will beobserved that by means of the present improvement, the pull on the linksis in a straight direction lengthwise thereof and that the straightportions 3 and A are not only spaced from each other in each link, butthe adjoining straight portions of the several links are likewise spacedfrom each other a considerable distance, as at 17, and that although thespace between the straight portions of a pair of adjoining links is notas great as the space between the straight portions of each link, yet itis sufficiently great to give increased support to the stuffed mattressplaced upon the fabric. In other words, by reason 'of the fact that thestraight portions of adjoining links are spaced apart a considerabledistance, increased support is given to the mattress, as will be obviousas compared with the support which is given thereto should such straightportions be brought close together, for in such latter case a pair oflinks, for instance, would support the mattress practically only atthree points, whereas in the present instance the mattress issupportedat four points. Moreover, by reason of the fact that the hooksof each link are in alinement with the straight portions, there is noappreciable tendency of the links to draw the edges of the fabric towardthe middle and present an uneven edge, which is always a seriousdisadvantage in any fabric. Moreover, by reason of the fact that thehooks of each link are practically completely closed when formed, andbefore the fabric is assembled, the links can be quickly interwoven, andfurthermore when the links are tinned, the tinning material connects thehooked end with the adjacent portion of the link, thus formingpractically an integral loop.

By reason of the present improvement considerable resiliency is obtainedboth lengthwise and sidewise of the fabric.

One of the advantages, as hereinbefore stated, for the presentimprovement, is that the links may be quickly and readily formed bymachinery just as shown in the drawings, that is with closed hooks orloops, and readily and quickly assembled by inexpensive labor, thusavoiding the necessity of bending the ends to form the hooks subsequentto the assembling of the links.
